Abstract: In oil-water two-phase flow measurement, a capacitance-conductance sensor has been designed based on the fact that the capacitance sensor and conductance sensor realize the water holdup measurement in different situations with different sensitive ranges. Electrical switches are used to switch the two measurement methods at high speed in order to make them have the same sensitive fields. The disigned sensor realizes the whole fraction measurement in oil-water two-phase flow with low conductivity water (tap water) and the water holdup measurement error is less than 5[WTB4]%[WTBZ].

Key words: oil-water two-phase flow, capacitance-conductance sensor, water holdup measurement, sensor optimization
